Metatranscriptome profiling of a harmful algal bloom [PDF]

Harmful Algae, 2014
Metagenomic methods provide a powerful means to investigate complex ecological phenomena. Developed originally for study of Bacteria and Archaea, the application of these methods to eukaryotic microorganisms is yet to be fully realized. Most prior environmental molecular studies of eukaryotes have relied heavily on PCR amplification with eukaryote ...

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

Wildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Trend of harmful algal bloom dynamics from GOCI observed diurnal variation of chlorophyll a off Southeast coast of China

Frontiers in Marine Science
Timely and accurate observations of harmful algal blooms dynamics help to coordinate coastal protection and reduce the damage in advance. To date, predicting changes in the spatial distribution of algal blooms has been challenging due to the lack of ...

Isolation and Characterization of a Double Stranded DNA Megavirus Infecting the Toxin-Producing Haptophyte Prymnesium parvum

Viruses, 2017
Prymnesium parvum is a toxin-producing haptophyte that causes harmful algal blooms globally, leading to large-scale fish kills that have severe ecological and economic implications.

Harmful Algal Blooms in Coastal Upwelling Systems [PDF]

Oceanography, 2005
14 pages, 9 figures The California Current, Humboldt Current, Canary Current, Iberian Coastal System, and Benguela Current represent five Large Marine Ecosystems (LMEs) associated with eastern boundary upwelling regimes (Figure 1). LMEs are characterized by distinct bathymetry, hydrography, productivity, and trophically dependent populations.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, EarlyView.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Evaluating Bias in Self-Reported Symptoms During a Cyanobacterial Algal Bloom

Toxins
Algal blooms produced by cyanobacteria liberate microcystins and other toxins that create a public health hazard. During the 2018 bloom of Microcystis aeruginosa in Florida, USA, residential and recreational exposures were associated with an increased ...

Canine Cyanotoxin Poisonings in the United States (1920s–2012): Review of Suspected and Confirmed Cases from Three Data Sources

Toxins, 2013
Cyanobacteria (also called blue-green algae) are ubiquitous in aquatic environments. Some species produce potent toxins that can sicken or kill people, domestic animals, and wildlife.

Natural‐based antioxidants in cosmeceuticals: Extraction, bioavailability and skin ageing applications

International Journal of Cosmetic Science, EarlyView.
Natural antioxidants from plants, fruits, seeds and fungi combat ageing by neutralizing free radicals, boosting collagen and protecting against UV damage. Enhanced by green extraction and smart delivery systems, they offer powerful anti‐inflammatory and antimicrobial benefits.

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...
